* Merge commit c80c09f3e380 from llvm-project (by Dimitry Andric):Dimitry Andric2024-07-281-5/+6
| | | | | | | | | | | | | | | | | | | | | | [CalcSpillWeights] Avoid x87 excess precision influencing weight result Fixes #99396 The result of `VirtRegAuxInfo::weightCalcHelper` can be influenced by x87 excess precision, which can result in slightly different register choices when the compiler is hosted on x86_64 or i386. This leads to different object file output when cross-compiling to i386, or native. Similar to 7af3432e22b0, we need to add a `volatile` qualifier to the local `Weight` variable to force it onto the stack, and avoid the excess precision. Define `stack_float_t` in `MathExtras.h` for this purpose, and use it. This is the version of the fix for PR276961 that landed upstream. PR: 276961 Reported by: cperciva MFC after: 3 days
* Revert "Fix llvm register allocator for native/cross build differences"Dimitry Andric2024-07-281-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for applying the fix that landed upstream, this reverts commit 397c2693fa66508cb5e6b173650a1f3bc6c4dd4f: Fix llvm register allocator for native/cross build differences Work around an issue in LLVM's register allocator, which can cause slightly different i386 object files, when produced by a native or cross build of clang. This adds another volatile qualifier to a float variable declaration in the weightCalcHelper() function, which otherwise produces slightly different float results on amd64 and i386 hosts. In turn, this can lead to different (but equivalent) register choices, and thus non-identical assembly code. See https://github.com/llvm/llvm-project/issues/99396 for more details. Note this is a temporary fix, meant to merge in time for 13.4. As soon as upstream has a permanent solution we will import that. PR: 276961 Reported by: cperciva MFC after: 3 days

| | | | | | | | | | | | master 2e10b7a39b9, the last commit before the llvmorg-12-init tag, from which release/11.x was branched. Note that for now, I rolled back all our local changes to make merging easier, and I will reapply the still-relevant ones after updating to 11.0.0-rc1.

This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
